R help - Dec 2015 - R-help mailing list

Hi


?
I am a PhD student and I want to learn how to run Linear regression with Lag-5
on R through "For Loop". Please find the details below:


?
1- ? ? ? ? ? ?I need guidance about Coding/ Programming for Simple Linear
Regression with Lag-5 on R.

2-???????????I have time series data of ?Daily Returns? of 15 stocks and I want
to see how each stock?sreturn is connected to all other stocks? returns. This
means, I have to runregression as follows:


?
? ? ? ? ? ? ? ? ? ? a) Impact of Stock 1?s return on return of Stock 2. Impact
of Stock 1?s return onreturn of Stock 3. Impact of Stock 1?s return on return of
Stock 4 ??? tillreturn of Stock 15.? ? ? ? ? ? ? ? ? ? b) Then, Impact of Stock
2?s return on return of Stock 1. Impact of Stock 2?sreturn on return of Stock 3.
Impact of Stock 2?s return on return of Stock 4??? till return of Stock 15. And
this will continue till Stock 15, one after another.? ? ? ? ? ? ? ? ? ? c) ?As
the the process will have to be repeated, therefore instead of manual coding
everytime, ?For Loop? is required.?



?
I shall bereally grateful for a detailed reply.


?
Thanks.

You need to start with a basic understanding of how R works. Here are
a couple of sources that might help you get started:
